    abstract = {Soils in the highlands of Ethiopia usually have low levels of essential plant nutrients and low organic
matter content especially low availability of nitrogen that has been demonstrated to be the major constraint to
cereal production. Nitrogen fertilizer application is among the most critical decisions for barley production due
to its large impact on growth, development and yield of the crop. Therefore, a field experiment was conducted
at Jimma University, College of Agriculture and Veterinary Medicine. The objective was to evaluate the effects
of N application rates on growth and development of food barley. The experiment was laid out in a Randomized
Complete Block Design (RCBD) with three replications having four nitrogen levels (0, 46, 66, 92 kg N/ha). The
results of the study indicated that N application rates had a significant influence on some growth parameters
studied and non significant on other. The maximum fresh weight (7.60 g) was recorded from the treatment that
received the highest N rate (92 kg/ha) and the lowest fresh weight (7.48 g) was obtained from the control plot.
These indicate that treatment four are recommended for the end users because as plant height and fresh weight
increase the end product is also increase. Similarly, the lowest (86 cm) and the highest (78 cm) plant height were
recorded from the treatments that received 0 and 92 kg N ha, respectively, indicating that N was a major growth
limiting factor for barley production. On the other hand, the effects of N application rates on tiller number,
length of spikelet and number of kernels were found to be significant.}
